EPS_Java Projec is JAVA program can display charts, and Handle waypoints, track, and routes. It reads output from the gpstrans program. gpstrans can communicate with Garmin GPS navigators.
Motoko it s a 2D library to Handle the graphical user interface of the game. It supports the basic controls of the windows GUI look like: PictureBox, TextBox, ListBox, LabelBox, ControlListBox, ComboBox, Button, CheckButton, Dialog, Panel, HScrollBar and VScrollBar. It uses the library CRM32Pro, so the CRM32Pro devkit will be needed to develop any application with Motoko, and it s contained in the Motoko devkit. The Motoko library is under the LGPL license, so read first the license if you want to make any change to the library.
When working with mathematical simulations or engineering problems, it is not unusual to Handle curves that contains thousands of points. Usually, displaying all the points is not useful, a number of them will be rendered on the same pixel since the screen precision is finite. Hence, you use a lot of resource for nothing!
This article presents a fast 2D-line approximation algorithm based on the Douglas-Peucker algorithm (see [1]), well-known in the cartography community. It computes a hull, scaled by a tolerance factor, around the curve by choosing a minimum of key points. This algorithm has several advantages:
這是一個基于Douglas-Peucker算法的二維估值算法。
The control uses javascript to Handle number formatting as you keep typing and does the validation as well. For one of our requirement, we needed a javascript based control that did formatting as the users kept typing. Google search only yielded script that did formatting on focus change events only. So I went about creating a new control myself.
